added so called "breadcrumbs" - little linkbars which help you find your way back to the homepage... looks a bit annoying at first sight, its supposed to help a lot on search engine results, so I'm giving it a shot.
got quite some first-page hits from google, SEO-works seem to show some effort. At least, google has decided "track" and "backing" are the two most important key terms about wikiloops... man, three weeks work to get that :)
only bing and yahoo dont seem to like wiki at all, got only negative signals from their admin interface, cant really get why. oh well.
if anyones annoyed by the breadcrumbs, I might as well hide them for logged-in users - on the other hand, they might turn out to be helpful sometimes :)
